Abstract

A highly sensitive and stable choline sensor based on the synergetic effect of multi-walled carbon nanotubes and ZnO nanoparticles has been developed. This nanomaterials-based choline sensor was highly sensitive and showed good stability over a relatively long-term storage (90 days). The sensor prepared showed a linear response range of 1.0 μM to 0.8 mM, a sensitivity of 178 μAmM-1 cm-2 and a detection limit of 0.3 μM.
